Fuel Tank Filtering and Cleaning

Fuel Tank Filtering and Cleaning: - Follow the example below for fuel filtering / tank cleaning Protocol and perform similar procedure on each tank listed below: Fuel Filtering / Tank Cleaning Protocol - Remove drop tube and monitor system probe from tank to gain as much access as possible. - Grounding system is attached to fuel tank. - Pump out water and sludge from all access points. - Pump up fuel from low end using a 2" hose. - Return fuel to the high end using a 1 1/2" hose. - Fuel passes into a vessel, which has Velcon paper filters. Filters may be 25-micron down to 1 micron to obtain the ASTM standard 0.05% Max. water and sediment. - Fuel exits clean side of filter vessel, then through a water separator and through a gallon meter so the quantity of fuel filtered is measured. - Fuel is polished at a rate of approximately 70-gallons per minutes (4200 gallons per hour). - There is a sump on the dirty side of the filter vessel where sludge and other contaminates are removed by the technician every 15-20 minutes depending on how contaminated each tank is. - When the technician feels the tank is clean and contamination is removed, hoses and stingers are removed from the tank, filter vessel is drained through filters and an after sample is taken off the bottom of the tank and put into a clear bottle so the customer may have a visual sample. - Grounding system is removed from tank. Drop tube and monitor probe are put back into tank and back into service. - Filter the fuel in the 200-gallon belly tank for emergency generator for Building 10. - Filter the fuel in the 1,000-gallon unleaded above ground fuel tank for building 44. - Filter the fuel in the 500-gallon red diesel above ground storage tank for building 44. - Filter the fuel in the 200-gallon red diesel generator belly tank for building 99. - Filter the fuel in the 5,000-gallon red diesel in ground storage tank for building 200. - Filter the fuel in the 2,000-gallon red diesel in ground storage tank for building 201. - Collect samples from each tank after filtering and send to Laboratory for Analysis IAW the requirements of NFPA 110.
